If your iPhone 4s screen is cracked, broken, or just not looking as good as it used to, there are a few steps you can take to replace it. The first thing you’ll need is a replacement screen. There are a few different options available online and at most electronics stores. The most common replacement screens are made of glass and plastic, but there are also metal replacements available. Once you have the replacement screen, the next step is to remove the old screen from your iPhone 4s. This can be done by gently pulling on the edges of the screen until it comes free from the phone body. Once the old screen is removed, place the new one in place and reattach the edges of the screen using gentle pressure. Make sure that all of the connections between the new and old screens are secure before closing up your iPhone 4s case or putting it back in your pocket. ..
